What will it take to get skeptics to warm up to climate change?

Demonstrators form a sit-in during a march towards Wall Street from Battery Park to protest for action on climate change and corporate greed, in New York, Monday, Sept. 22, 2014, a day after a huge climate march in the city.

As the annual United Nations climate talks get under way Monday in Peru, global leaders are likely to call out natural disasters like Hurricane Sandy in a bid to rally support for a pact combating global warming.

But a new study finds that extreme weather - whether it be droughts, floods or heat waves - does little to change attitudes about climate change in the United States.

Climatic conditions "only have a negligible effect on perceptions about the seriousness of climate change," the researchers wrote in a study published in Global Environmental Change. "These results suggest that further changes in climatic conditions are unlikely to produce noticeable shifts in Americans' climate change perceptions."

Rather, it comes down to personal politics.

"Our results show that political orientation has the most important effect in shaping public perceptions about the timing and seriousness of climate change,"

One survey found that only 46 percent of Americans felt there was serious impact now from climate change and 28 percent felt global warming would have serious impact in the future. Three in four Republicans didn't feel global warming will be a threat to them personally; 56 percent of Democrats felt it would.

With such divided opinions on the issue, Congress has been unwilling to seriously consider any solutions to combating rising emissions.

In the Global Environmental Change study, researchers used data from the National Oceanic and Atmospheric Administration's climate extreme index and Gallup Poll data on climate change. They found no link between exposure to extreme weather and views on global warming.

"All the authors on the study went in expecting some correlation," Michigan State's Aaron M. McCright, one of the authors of the study, told CBS News. "I certainly thought we would find really warm summers would be related to climate change or really warm winters. I thought we would find a smattering of effect and we didn't find anything."

The study also examined earlier research on the issue and came to a similar conclusion. Some of those past studies, McCright said, found a small effect in terms of people "believing in the reality of climate change." But they also found the more partisan person was, the less they saw a connection with extreme weather.

"Many people already had their minds made up about global warming and this extreme weather was not going to change that," McCright said of the winter, which was the fourth warmest winter in the United States dating back to at least 1895.

Christopher Warshaw, an assistant professor of political science at MIT who is also studying climate change attitudes, said it made sense that politics trumps almost everything else when it comes to global warming.

"There is a huge body of scholarship in which people sort of internalize external events through a partisan lens," Warshaw said. "People's views on whether wars are a good idea shift completely when the party in power changes. In some ways, it would be more surprising that climate change didn't work that way."

Part of the resistance to changing one's views, Warshaw said, is that action on climate change will require a big role for government which is seen very differently by Democrats and Republicans.

"Certainly on the left, your ideological predisposition is to support more government action. The fact the government will have to do something about climate change doesn't challenge your prior believes about the role of government in the world," he said. "Whereas if you are conservative, you believe the government shouldn't do much. The fact the government will have to take a lot of action to address climate challenges your core beliefs about the role of government in the world a little bit."

Studies have found that extreme weather is expected to become more common and intense in the future. A report out Thursday from the Royal Society, the national academy of science in the United Kingdom, concluded that extreme weather cost $1.4 trillion, total, between 1980 and 2004. Looking ahead, it projected large coastal cities could face a combined cost of $1 trillion each year from flooding by mid-century.

So if extreme weather won't change views about climate, what will?

McCright said change would only come on the right when leading Republicans and opinion makers come around to the fact that climate change is real, acknowledge it is caused primarily by humans and start speaking out about it.

"We need key members of the Republican party and key Republican media figures to ease up on climate denial a little, just stop denouncing science and scientists and, over time, be more accepting of the science," McCright said.

Warshaw also said it would help if Republicans saw an economic cost to inaction or see the solutions to reducing carbon emissions as being relatively cheap.

"As the costs of wind power and solar power becomes cheaper to address climate change, I think public opinion on taking action on climate change will change," he said. "People are attentive to cost."
